Typical Antenna Gain / Factor

This is calculated by reference to standard gain horn antennas, and cross checked with reference to the antenna beamwidth, with an estimated error of +/- 0.8dB.

Patterns measured using a linear source antenna , Horizontal / Vertical refers to the polarisation of the source horn.

 On patterns the Red & Black trace  = Horizontal polarised source, Green & Blue trace = Vertical polarised source

Pattern Cut Definition

Patterns are measured using a linear source antenna. The polarisation refers to the electric field polarisation of the source antenna.

Horizontal Cut (Cut 1) Vertical Cut (Cut 2)

Antenna viewed from back

  • Red trace  = Sweep with horizontal source polarization and antenna under test in horizontal cut (cut 1)
  • Blue trace = Sweep with vertical source polarization and antenna under test in horizontal cut (cut 1).
